Fuel Surcharge Calculator
Diesel goes up, your margin goes down. Bill the difference correctly.
Compute fuel surcharge per mile and total dollars on a load using any of three industry-standard FSC programs. The DOE-classic formula divides the diesel-price spread above a base by the truck MPG. The step-matrix program (used by Schneider, Werner, JBHunt, and most major shippers) rounds down to a published $/mile cell every X $/gal above base. The flat percentage program multiplies a fixed percent of linehaul revenue. The calculator shows side-by-side what each program would have paid on the same load, charts the effective $/mile across a diesel-price range, and computes margin protection so you can see exactly how much fuel risk the FSC is absorbing for you. Use it before signing a shipper contract, when bidding on a load board lane, or just to verify a broker is paying the FSC the rate confirmation says they will.

Pick the program type
Standard (DOE-classic) is the per-mile formula most owner-operators use when they have their own authority. Step-matrix is what large shippers publish as a rate-confirmation table. Flat percent is occasionally used by brokers and some 3PLs. The calculator handles all three, plus shows what the other two would have paid on the same load.
-
Enter current and base diesel prices
Current diesel = the DOE weekly national retail average (or your local pump price, if you prefer). Base diesel = the price at which FSC equals zero. Standard formula uses $1.20 to $1.25 per gallon as the historical base. Step matrices typically use $1.50 to $2.00. The base is whatever the shipper or contract specifies.
-
Enter truck MPG
Use your weighted MPG (loaded miles plus deadhead, weighted by mile share). For Class 8 OTR, 6.0 to 6.5 MPG is typical. For hot shot 1-ton + gooseneck, 11 to 14 MPG loaded, 16 to 19 empty. The DOE-classic formula divides by MPG, so the lower your MPG, the more FSC you collect.
-
Enter loaded miles, total miles, and FSC paid-on basis
Total miles = loaded plus deadhead. FSC Paid On determines the basis: most contracts pay FSC on loaded miles only, but some pay on all miles run for the shipper including deadhead to and from the pickup. Read the contract carefully.
-
For step matrices, enter the interval and rate
Common matrices step at $0.04 to $0.06 per gallon, with $0.01 per mile per step. So a 6 MPG truck at $5.00 diesel against $2.00 base ($3.00 over base, 4 cents per step at $0.04 = 75 steps, $0.01/mi each) earns $0.75 per mile. Compare this against the DOE-classic ($3.00 / 6.0 = $0.50 per mile) to see whether the matrix is paying you correctly.
-
Read the side-by-side reference table
Three reference programs (DOE-Classic, Shipper Step Stiff, Shipper Step Fair) compute on the same inputs so you can see at a glance which programs over- or under-pay. Use the chart to see how the effective rate (linehaul plus FSC, per mile) holds up as diesel rises. A flat dashed red line marks where you would be without an FSC at all.
Built For
- Owner-operator pricing a load against a known shipper FSC matrix and verifying the matrix is fair
- Carrier or 3PL contract negotiation comparing the proposed FSC program against the standard formula
- Accountant or controller verifying an invoice line for FSC matches the contract program
- Owner-operator deciding whether to accept a load with no FSC (linehaul-only flat rate) when diesel is rising
- Hot shot operator setting their own FSC for direct-customer bidding on Permian or Bakken work
- Broker writing rate confirmations and explaining the FSC component to a small carrier
- New owner-op understanding why their take-home dropped when diesel jumped from $4 to $5 even though the load board rate did not change
Features & Capabilities
Three Industry-Standard Programs
DOE-classic per-mile formula, step matrix (carrier rate confirmation pattern), and flat-percentage of linehaul. Switch between them with one click. The same inputs feed all three.
Side-by-Side Program Comparison
Three reference programs show what each would have paid on the same load: DOE-Classic, Shipper Step Stiff, and Shipper Step Fair. Use this to see whether a shipper FSC quote is fair or shifting fuel risk onto you.
Effective Rate Chart Across Diesel Range
A line chart shows how the effective $/mile (linehaul + FSC) rises with diesel price from $2.50 to $6.00. A horizontal dashed line marks the without-FSC rate. The current diesel price gets a marker. Use it to communicate fuel risk to a customer or driver.
Margin Protection Output
Tells you in dollars per mile and total per load how much margin the FSC is protecting. A heavy FSC ($0.50 per mile or more) is real money against fuel volatility. A light FSC ($0.10 per mile or less) is symbolic.
Verdict Tier Coloring
No FSC, Light, Standard, Heavy, and Severe tiers based on the FSC per mile output. Helps you communicate FSC magnitude to customers and dispatchers without quoting raw numbers.

Comparison
| Program | Formula | Common Use | Pays Carrier Best When |
|---|---|---|---|
| DOE-Classic | ($current - $base) / MPG | Owner-op direct contracts | MPG is low (heavy truck) |
| Step Matrix | ⌊($current - $base) / step⌋ × $/mi | Large shipper rate confirmations | Step interval is small ($0.03-$0.04) |
| Flat Percent | % × linehaul revenue | Some brokers, 3PLs | Linehaul rate is high |
